NAME

       networkctl - Query the status of network links

SYNOPSIS

       networkctl [OPTIONS...] COMMAND [LINK...]

DESCRIPTION

       networkctl may be used to introspect the state of the network links as seen by
       systemd-networkd. Please refer to systemd-networkd.service(8) for an introduction to the
       basic concepts, functionality, and configuration syntax.

OPTIONS

       The following options are understood:

       -a --all
           Show all links with status.

       -h, --help
           Print a short help text and exit.

       --version
           Print a short version string and exit.

       --no-legend
           Do not print the legend, i.e. column headers and the footer with hints.

       --no-pager
           Do not pipe output into a pager.

COMMANDS

       The following commands are understood:

       list [LINK...]
           Show a list of existing links and their status. If no further arguments are specified
           shows all links, otherwise just the specified links. Produces output similar to:

               IDX LINK         TYPE     OPERATIONAL SETUP
                 1 lo           loopback carrier     unmanaged
                 2 eth0         ether    routable    configured
                 3 virbr0       ether    no-carrier  unmanaged
                 4 virbr0-nic   ether    off         unmanaged

               4 links listed.

           The operational status is one of the following:

           off
               the device is powered down

           no-carrier
               the device is powered up, but it does not yet have a carrier

           dormant
               the device has a carrier, but is not yet ready for normal traffic

           carrier
               the link has a carrier

           degraded
               the link has carrier and addresses valid on the local link configured

           routable
               the link has carrier and routable address configured

           The setup status is one of the following:

           pending
               udev is still processing the link, we don't yet know if we will manage it

           failed
               networkd failed to manage the link

           configuring
               in the process of retrieving configuration or configuring the link

           configured
               link configured successfully

           unmanaged
               networkd is not handling the link

           linger
               the link is gone, but has not yet been dropped by networkd

       status [LINK...]
           Show information about the specified links: type, state, kernel module driver,
           hardware and IP address, configured DNS servers, etc.

           When no links are specified, an overall network status is shown. Also see the option
           --all.

           Produces output similar to:

               ‚óŹ      State: routable
                    Address: 10.193.76.5 on eth0
                             192.168.122.1 on virbr0
                             169.254.190.105 on eth0
                             fe80::5054:aa:bbbb:cccc on eth0
                    Gateway: 10.193.11.1 (CISCO SYSTEMS, INC.) on eth0
                        DNS: 8.8.8.8
                             8.8.4.4

       lldp [LINK...]
           Show discovered LLDP (Link Layer Discovery Protocol) neighbors. If one or more link
           names are specified only neighbors on those interfaces are shown. Otherwise shows
           discovered neighbors on all interfaces. Note that for this feature to work, LLDP= must
           be turned on for the specific interface, see systemd.network(5) for details.

           Produces output similar to:

               LINK             CHASSIS ID        SYSTEM NAME      CAPS        PORT ID           PORT DESCRIPTION

               Capability Flags:
               o - Other; p - Repeater;  b - Bridge; w - WLAN Access Point; r - Router;
               t - Telephone; d - DOCSIS cable device; a - Station; c - Customer VLAN;
               s - Service VLAN, m - Two-port MAC Relay (TPMR)

               1 neighbors listed.

       label
           Show numerical address labels that can be used for address selection. This is the same
           information that ip-addrlabel(8) shows. See RFC 3484[1] for a discussion of address
           labels.

           Produces output similar to:

               Prefix/Prefixlen                          Label
